As is wellfknown paint, varnish and the like are sold in large` quantities in air-tight vtin or` contents must be thoroughly stirred in order to bring the contents back to a homogeneous mass. Since these containers are usually filled when-received by the consumer, itis exceedinglyidifiicult to stirthe contents sufciently without spilling or splashing some of the contents from the receptacle. Y p' It is the purpose of the present invention to provide efcient means for thoroughly mixingk said contents withoutfsaid spilling or splashing, and at the same time providing rne'ans'whereby said container shall remain hermetically'esealed until it is desired to use said contents. The inventionalso provides improvements indetailsr of construction. Y

Referring toV the drawing which illustrates merely by way of example, 4a suitable embodiment of the invention. I

Fig. 2 is a fragmentary planview of same.

Fig. 3 is a vertical'section showing a modiica-` tion of the stirring element.

Figs. 4 and 5 are fragmentary sections on enlarged scale, showing modications in means for disengageably attaching the actuating element.

Fig. 6 is a fragmentary .View in elevation, indicating the method oi opening the container.

vSimilar numerals" Arefer to similar parts throughout the several views.

The usual form of container for paint, varnish and the like in small amounts, is the tin canas indicated by 8, in Fig. 1. 'I his can is provided with a closure-or lid 9 having a portion l0 fitting v'ard dictionaries.

spending opening 18r ofthe actuator. y .i Fig'. 5 is` shown a stud provided with a threadedso `end `19 for engaging in a correspondingthreaded curing disengageable locking cooperation between in the manner described for removing the lid or I .'Ilhis lid, accordance withthe present invention in its simplest form, is provided with a centrally disposed'opening'or hole 11 for` receiving theprojection 12 yof the stirringelement 13. For

purposesof transportation and storing, the space Y601 r -between themargin of the opening 11 and the roe' tatable projection `12 therein, is hermeticallyl sealed bysolden'as at 14, or Aother material softer 'than the surrounding and surrounded parts, so

that 'this seal, while normauyrigid, will release the 65 smooth shaft or projection 12, when sufficient torsional forceA is applied thereto. The termsolder is used in this application, as dened in the stand- This projection 12 is providedwith means for 70 disengageable engagement with a suitable actuating element 15. In the example shown in Fig. 1,I this comprises a holeV 16 in projection 12 for receiving the end of actuating element 15e;

lIn Figs. 1i. and'5 are shown modifications means for disengageably connecting the actuator with the projection or stud12. vIn Fig. 4 an angu e lar end-ll'i'sprovided for engaging in a corre- While inA openingl 20 of the actuator; v A j Other means may ofcourse be provided forse-v thereof, as at 21, so that the'opposite parts thereof shall be inclined to the horizontal or plane oi?V i the bottom of thev container. These inclinations are adapted to lift the heavier material from the bottom of the can when the stirrerisrrotated in the clockwise direction.v

The, upwardlyinclined extensions or sides 22 I of the triangle may have Ytheir nat planesvradially disposed, or`,as shown in the drawingthey may be slightly inclinedto the radial plane, to cause a movementof the material away therefrom and upwardly, Vwhen the stirrer is rotated in clockwise direction;V i Y The actuator 15 is a tapered or` sharpened end 23 for insertion between the flange 24 and margin 25:0f the licl and shown also as provided with can, respectively, as shown in Fig. 6, so thatafter v the stirring operation, the actuator l5 may be disconnected from the projection 12,;and then usedA ,110

tation. Other means of course may be employed 1 for connecting Vthe keeper to the "container VV*for transportation.

The actuatorlis preferablv bent as shown in kFig. 1, to facilitatefthe engagement thereof with projection 1'2,.and-'s`o thatthe-fiee end. may ,ex-,

tend over` the flange of the lid While maintaining the vpart engaging therprojection 12 horizontalposition. This form ofV actuator alsosecures a wedging pressure engagement with keeper 26 when the actuatoris packedffo'r shipment.

A special advantage ofthe triangularformation of the stirring, element-131, shownlin Fig'.` 3", is that the upwardly inclined extensions 22 and ythe'inclined lfaces of the lower extensionrrofv said Ythrough the closure, manually operated means for actuating the shaft and means, comprising a/solder joint," forrning a normally rigid hermetic seal between the shaft andthe surrounding wall of the closure, adapted to release the shaft upon the application off torsional' force thereto.
